HATCH ET TOOL-HOLDER.

Specification of Letters Patent.

Patented March 12, 1907.

.To a whom it may concern:

Be it known that I, PArRrcK F. GALLA- GHER, a citizen of the United States of America, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Ratchet Tool-Holders, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in ratchet tool-holders, and the invention relates more particularly to a die or drill holder equipped with a novel form of ratchet.

The primary object of my invention is to provide a tool-holder having a ratchet-lever which can be easily and quickly revolved, and in this connection the holder may be adapted to support a thread-cutter or a drill or bit or other tool according to the manner in which the device is used.

The device may be readily used as a wrench, and the ratchet mechanism which I use in connection with the device permits of it being used in difficult places where it would be impossible to rotate a thread-cutter or wrench. For instance, my improved device when used as a thread-cutter is particularly adapted for cutting threads upon the ends of a bursted gas or water ipe, especially where the pipe traverses a wa l or floor and where it is impossible to elevate the pipe sufficiently to permit of the rotation of an ordinary thread-cutter.

I have constructed my improved device upon simple and inexpensive lines, and the comparatively few parts employed ermit of the device being easily and quick y assembled or adjusted according to its various usages. The device is also provided with an attachment whereby it can be used as a drill and bit holder, and the many other advantages of the device will be apparent from the following description, taken in connection with the claim.

Referring to the drawing accompanying this application, like numerals of reference designate corresponding parts throughout the several views, in which- Figure 1 is a side elevation of my improved implement. Fig. 2 is a bottom plan of the same. Fig. 3 is a plan of a tool or drill holder used in connection with my improved ratchet tool-holder.- Fig. 4 is a sectional view of the same. Fig. 5 is a fragmentary horizontal sectional view of a portion of my improved implement. Fig. 6 is a plan of the detachable sleeve. Fig. 7 is a side elevation of the same. Fig. 8 is a side elevation of my improved implement equipped with a feed extension. Fig. 9 is a vertical sectional view of my improved implement.

To put my invention into practice, I con struct the improved implement of a cylindrical body portion 1, having a central bore 2. The periphery of the body portion 1 centrally of its ends is provided with circumferentially-arranged ratchet-teeth 3, While one end is provided with a die-holding collar 4. The collar is formed with a rectangular recess 5 to receive a drill or bit holder 6, which is substantially rectangular in plan and is provided with a bore 7 to receive the shank of a bit or drill. (Not shown.) In lieu of the drill or bit holder 6 the rectangular recess 5 may be provided with threaded cutting-dies, which can extend into said recess through diametrically-opposed openings 8 8, formed in the collar 4. The periphery of the collar is threaded, as at 9, to receive a cap 10, employed for retaining the drill or bit holder 6 within the recess when the same is being used. The opposite end of the cylindrical body portion 1 is provided with a screw-threaded recess 11 to receive a threaded collar 12 or a threaded extension-screw 14, said extensionscrew being similar to extension-screws heretofore used in connection with drills.

The formation of the collar 4 and the peripheral teeth 3 provides an annular groove 15, and engaging in said groove is a semicircular strap or yoke 16, carried by a handle or operating-lever 17. To secure the strap or yoke upon the body portion of the ratchet, I employ a sleeve 18, which fits over the cylindrical body portion 1 and engages the edges of the teeth 3. The sleeve 18 is provided with a pierced extension 19, by which it is fastened to the handle or operating-lever by pins or screws 20.

I The end of the handle or lever 17 adjacent to the body of the ratchet has its edges recessed, as at 21 21, and pivotally mounted in said recesses are pawls 22 and 23, said pawls lying in close proximity to the edges of the handle or operating-lever 17 and extending forwardly to engage the teeth 3 of the body portion 1. The rear ends of the pawls 22 and 23 are normally held outwardly by springs 24 24, mounted in recesses 25 25 of the handle or lever 17. These springs normally retain the forwardends 'ofvthe pawls in engagement with the teeth 3, and in order that the improvedimplement may either be rotated to the left or to the right I provide the handle or lever 17' with a movable'locking-band 26. The band is retained in en gagement with the handle or lever 17 by a pin 27, which extends througha circumferentiallyarranged slot 28, formed in saidsleeve. The edge of the sleeve yadjacentito the rear ends of thepawls .22iand 23,:is-cut away, forming a flange 29, :whichvis-moved into engagement with either one ofthe pawls 22 or 23 bytrotating the locking-band;,26.

From the foregoing description it will ,be observed that :the handle: or operating-lever 17 of the implementis,lockedinengagement with the body'portion 1 thereof by-the strap or yoke 16 and the detachable sleeve 18, which is mounted upon the ibody portion 1 and connected to the handle or lever 17 in the course of assembling the variousparts. of my improved implement.

In operation whenit is desired to rotate the implement tothe right one of'the'pawls 22 or 23 is locked out of. engagementwith: the

ratchet-teeth of the body portion 1 by rotating the locking-band 26. 1111 "rotating the band'the rear end'of one oftthepawls is:depressed, consequently elevating the forward end and onlyv permitting its associate rpawl to engage the teeth ofthe bodyportion 1.

Such changes in the construction and operation of "my improved implement as are permissible by the appended claim may be resorted to without departing from the spirit and scope of the invention.

What'I claim, and desire to secure by Letwere Patent, is

In animplement of the class described, a

stock having annularly-disposed ratchetteeth and an annular channel intermediate the ends, and withlmeansi at one endforsup:

porting; an oper-ating tool andiwith means at the otherend for supporting a holding bearing yin-said annular channel, asleeve bearing around said stock and against said annular. ratchet portion A at the side opposite from said yoke .-and ,provided with a lateral extension. engagingsaid, head 'meansfor fastenlng said extension to said head, paWls swinging in said recesses andengaging said ratchetteeth, and means for alternately opcratingsaid pawls.

;In testimony whereof I afiiXYmy signature in.thepresence of twowitnesses.
